Be it known that I, Jason WEIBENBERGER,

a citizen of the United states of America, and a resident oi.Corning, Nevv York, have invented certainnew and useful Im rovements "in t I nitial-Puff Mechanism, for, :rlassBlowing Machines, of which the following IS a specification. I

In Letters Patent No. 1,124,701, issued on an application of Benjamin D. Chamber- 'n for an apparatus for the produotion of blown glasserticles, there is idisclosetl means whereby an air pump isactuated from time to time to force air into a marveretl blank on the end of a glass carrying-blowpipe to expand the same, the actuation of the pump, for the purpose stated, following a movement of the blow-pipe from the marvering position. i

, M y invention relates-to a device designed to hefattached to such apparatus, and to tuate'the pump previous to the movement of the lJlOW plp8 from marvering position for causin the initial puff. i ln,t e accompanying drawings:-

15, the rises of the series of cam S b eing litent fl Mar- 2 radial in respect to the axis of. oscillation of the blowpipe -frame, the projeetions'are at right angles to such. plane: 1 1 f The blow-pipe frame comprises a skeleton extension formed by, pipes 116 and 17,

1 that carry an air cylinder 18. The cylinder designed to receive one'encl of the blowpipe 3, means being two to prevent escape of air, and passi through i rod 19, the inner end of mounted thereon a piston 20,,the rod bein surrounded by a spring 21 that forces the piston forwardly, The piston rod 19. has upon its outer end an upon the outside of the oylindera conical head 22 with whioh a laternll extending finger 23 on th outer end of a cooker rod 24 slidably mounted in the hlowhead resting and in bearings .on the liod of the biowto engage.

The inner end of the cooker rod is pro- 26. adapted to contact with and be ii the mine 8, 9, attached thei 'eto a laterally extending arm 27. having on the end thereof a roller,28, the projections 13,

i4 and 15, on the cam plate wherebythe rod will be given an angn'hirniotion. 1

The rod 2t has ,thus two trnotions in its hearings, the one the finger 23 is in 2) on the piston rod, retracts the other an'angular or rotary movement, whit-h disengng'os such finger from the head on the piston rod and permits the spring 21 to project the latter forward] engagement with the head lurt's similar to those above described are present in tho :1 ioresnid Patent No. 1.124.70L and heme lll'tll no further inscription;

Monnh-d on th rum plnti-i T. h means of a hravhrt il. is u rorloshuit 32. having; a laternll extruding :irm i-l at its outer end and n laterally (attending arm 34 at its inner end. \i the outer vn'd of thiurm 111i is :I roller 3-1 uhih= n1 ilnffllil'l' end oi the arm 11 is :1 pint lll fhlii normally lies in u lillSS 3T l'iu'riamlt i lhr l' llll plate T. i\ houdvrl stud Ill thrwni 'ii ii: the pinto Ill; and passing Kill n gh nu op ning Zi-i ll he rum plate T is onr ri-lwl hi on wxgmmi Ih' spring if). this on trmii m li ing slnh that the plate 36 'while the rises of provide for sealingthe:

pipe frame, is adapted od'with' n foot block 25. carrying a roller-j longitudinal, which, when 1 w the latter. and

thehead of the, cylinder is a piston which has slidably.

ft d by l0, l1; en'd12, nndhas alsoQ will be retained Within the spring 40.

The relative position of the plate 36 on the outer end of the arm 34 with respect to the roller 28 on the outer end of the laterally extending arm 27 of the cooker rod 24, is such that when the blow-pipe frame is in marvering position, the roller 28 is over the plate 36, and in contact therewith.

Asin Patent No. 1,124,701, the rotation of the cam disk in the direction of the full line arrow causes a reverse motion (see dotted ar row Figure 1) of the blow-pipe to marvering position, a pause of the blow-pipe at that position and finally a retrograde motion of the blow-pibe.

At the completion of the marvering operation, the relative position of the cam disk is such that a stud 5 on the face thereof will, on continued motion of the cam, engage roller on the outer end of the laterally extendin arm 33 of the shaft 32, and so doing will raise the arm 33, causing the shaft 32 to be rotated, and thereby raising plate 36 against the tension of spring 40, to the dotted line position shown in Fig. 2 of the drawings' By preference this is timed to occur before the blow-pipe frame has been moved from marvering position.

When plate 36 rises, it carries roller 28, thereby turnin the cooker rod 24. This will cause the uger 23 ,on the outer end of the rod 24 to be moved from its engagement with the head 22 of the piston rod 19. Inasmuch as the rod 24 was priorto this time and on the movement of the blow-pipe to marvering position, moved outwardly by the cam 8 (see Figure 1) the release of the piston by the rod results in the spring 21 causing the piston to move forward in the cylinder, and in a puff of air being forced into the marvered blank on the outer end of the blowpi e, as will be readil understood.

he movement of t e parts to create the puff in the blow-pipe-is momentary, and the continuing motion of the cam disk 6 carries the stud 5 past roller 35, and the parts are returned to their normal positions, the plate 36 returning to its seat within the recess 37 in the cam plate 7.

The blow-pipe frame is then set in motion, and the roller 28 will ride off late 36 directly on to the face of the cam will, as the blow-pipe frame'swmgs to vertical position ride over the proje ions 13, 14, and 15 to roduce otherpufl's'ofair in the blank, as 18 described in the aforesaid patent.

it will be noted that whereas the former patent required a movement of the blowpipe frame in respect to the fixed cam plate 7 to cause the initial pufl', this invention causes such pufl" by relative movement between the blow-pipe and the movable cam disk 6. This difference permits the puff to recess 37 by the late 7, and

follow the marvering more quickly and to take place while the blank is still in marvering position instead of after it is moved therefrom.
